  • "Inasmuch as the purpose of this investigation was to determine the aerodynamic effects associated with particular changes in canopy shape, rigid leading edges, keels, and spreader bars were used in order that a canopy shape under air load reasonably similar to that desired might more easily be maintained. In many practical applications, of course, it would be desirable to use the results obtained to design less rigid configurations that take greater advantage of the paraglider tension structure concept."
